Why haven’t scientists been able to develop vaccines against HIVand the common cold?
Comparing the number of infections, people catch cold so much more often than flu .Why haven’t we spent time and effort on developing vaccines to the cold virus ? a)The cold viral particle change over time, too difficult to develop a vaccine b)The cold viral remain stable over time and lose their ability to infect human over time c)The cold viral particle constantly change over time , catch a cold virus will result in vaccination for a long time d)There are too many strains of the cold virus and the symptoms are mild
Why should we make vaccines mandatory?
